A new Patron Tier is coming (Patreon)

I am going to add one more tier.  I always planned to have a $10 tier to be an option between the $5 and $30 ones - I just haven't decided what extra rewards to give that tier.  I'd like your feedback before I make a final decision.  Here's what I'm thinking:

The $10 tier could be called, "Hogwarts Alumni."  This tier will include all benefits of lower tiers plus the following benefits:

1) You can send me your designs to be featured in upcoming DIYs on my YouTube channel with a shout out to you and links to your website/social media page(s).

2) Free shipping on Etsy orders (within the US only).

Any ideas or thoughts?
